Specific embodiment
A kind of lathe tail platform torque Functional Design method based on digital control system is based under FANUC digital control system frame,
It is characterized in that the electric parameter of the electrical program of digital control system PMC is named and is arranged first, it is mutually powered-down referring to digital control system
Gas programming chart writes design for type lathe specific process logic, then to electrical program PLC ladder figure, makes electricity
Machine realizes position control and moment of torsion control free switching；See the electrical program of digital control system PMC used when Fig. 1 is calculated, position mould
Formula state, that is, axis servomotor mode and torque mode state, that is, PMC Axle mould formula are intrinsic configuration feature under FANUC digital control system frame,
It is servo Spindle Status that system, which just defaults tail platform motor: steps are as follows:
The first step, change following parameters switching activate another torque mode state of the axis servomotor: PMC Axle mould formula, more
Change as follows:
Digital control system parameter No. 1803 #4 are set as 1 expression function: tracking is executed under torque control mode；
Digital control system parameter No. 2007 #7 are set as 1 expression function: moment of torsion control executes；
No. 2105 curriculum offerings of digital control system parameter are 1 expression function: torque coefficient 1；
Digital control system parameter No. 2203 #4 are set as 1 expression function: employing mode when moment of torsion control；
Digital control system parameter No. 3105 #1 are set as 0 expression function: PCF is in actual speed is shown for expression, including PMC
The movement of control shaft；
2. after having changed system parameter, i.e., after activation tail platform motor PMC Axle mould formula；
Third step writes electrical program PLC ladder figure, i.e. electrical action logical order completes the top of tail platform in process
Tight process, referring to Fig.1.
PLC program illustrates (SUC8202S/1500 numerical control lathe tailstock platform part):
The first row: the model selection of the tail platform connection lamp address start-up and shut-down control tail platform motor of R1107.6；
Second row: the PMC axis of F130.0 in place the PMC axis motor message of signal and F130.4 while trigger conduct
The trigger condition of R131.7 intermediate address；
The third line: R0432.0 is automated manner M code and the point R1012.6 chuck button under manual mode, can trigger torsion
Torque motor (under PMC Spindle Status) advance effect；
Under fourth line is close with the third line overall logic and automatic running mode with operation manually is lower presses R1012.7 tail
Platform advance button can trigger torque motor (under PMC Spindle Status) and retreat effect；
Fifth line with the 6th row respectively when the triggering of corresponding three, four row and the movement reached；
In programmed logic judgement, reset is generally first carried out, retrogressing of reruning.Therefore design terraced the 7th row of figure indicates backward,
After torque motor advances in place, when holding torque, servo-system alarm is not caused if wanting to retract, program first generates reset signal
Afterwards, then back-off procedure is executed.
After having write electrical program PLC ladder figure, the following numerical value of setting is filled in PLC program parameter:
In conclusion completing the piece electrical design process of lathe tail platform Motor torque control.
Several explanations of programming:
1. the explanation of torque arithmetic:
Torque value unit is 0.00001Nm (unit is 0.001Nm when linear motor).When calculating motor stabilizing output
Torque it is as follows:
The torque constant that motor initialization generates in torque value=D2004 numerical value * 0.00001*2105.
Such as 8202S/1500 this series FANUC tail platform β type motor, value is 692 after the initialization of parameter 2105, torque value
It is set as 1500. tail platform output torques and is roughly equal to 10Nm.Torque=1500*0.00001*692=10.38Nm.
As FANUC other types motor aiS4/4000 type calculation method is also identical, it may be assumed that value is after 2105 initialization
127, output torque when torque value sets 500 are as follows: torque=500*0.00001*127=0.635Nm,.
It is required according to processing technology, the size of numerical value in also changeable PMC parameter D2004, i.e., adjustable tail platform output is turned round
The size of square value.
2. the explanation of way of torque:
It the use of the address D is D2000-D2007
D2000-D2001: type is byte, is set as hexadecimal, and wherein D2001 is mode IA, torque control
Mode processed instructs as 11H,
D2001 is that 11, D2000 is set as 0.(it can also be set to the decimal system, it is 17 that 11H, which is converted to the decimal system, so
It is set 17) in D2001.
D2002-D2003: type is word, and maximum feed speed is arranged in signed decimal number.
D2004-D2007: type is double word, and torque value is arranged in signed decimal number.
3. the explanation fast moved: the address D used is D2008-D2015:
D2008-D2009: type is byte, is set as hexadecimal, and wherein D2009 is mode IA, is quickly moved
Flowing mode is 00H, therefore D2009 is that 0, D2008 is set as 0.
D2010-D2011: type is word, and rapid traverse speed is arranged in signed decimal number.The speed of specified operation both can be with
It is worked out in PMC, the speed (sharing with CNC axis) set in parameter also can be used, depend on PMC axis relevant parameter (8001-
8028) setting.
D2012-D2015: type is double word, and moving displacement is arranged in signed decimal number.
Wherein symbol indicates to be positive number when positive direction to signed decimal number, and opposite direction need to only be set as negative when mobile；
D group supplemental characteristic format used and type set principle are FANUC OI TF system functional requirement, and application method is solid
It is fixed.
Design method of the present invention simplifies tail platform structure, there is the tail of the numerically controlled lathe of this lathe tail platform torque Functional Design
Platform structure, it is characterised in that: have tail platform, the tail platform top horizontal stationary center of triangle body on pedestal, pedestal is driven by motor.
Design method of the present invention also has started to be applied on 8202S/1500,8202L/2000 series numerically-controlled machine tool,
Such lathe eliminates brake portion, tripod, close switch and the extension sleeve part of original lathe tail platform, every lathe
Nearly 2 Wan Yuyuan of cost savings.
The more importantly thus inspiration of the design of the applied patent of item, and the invaluable experience obtained, can be the design in the future
Thinking migrates to other types lathe, provides successful story.
This application type patent of invention will be applied to 8202S/1500,8202L/2000,8202L/2500 and same class successively
Type lathe series.To the lathe series for not using this design, i.e. its tail platform part is locked and is braked using tradition machinery mode
Method, be provided with and replace and reduce the effect of cost.
Numerical control lathe tailstock platform part uses operational process update after new design as follows:
Motor is switched to torque mode state close to workpiece → by digital control system in advance by servo motor driving tail platform
(PMC Spindle Status) → motor drives the direct top tight workpiece of tail platform → motor keeps the value after arrival specific torsion → to wait to be processed.
